Polychem SA is a specifically developed, multi-component air-entraining admixture that has been stabilized to produce an air-void system that is consistent with industry requirements and standards. Polychem SA meets or exceeds the requirements of ASTM C260, CRD C-13 and AASHTO M154. Polychem SA is a synthetic-based alpha-olefin that will produce a small, more well-defined and spaced bubble structure. When added separately, it will produce an air-void system that is equivalent or exceeds that of pure Vinsol resin-based admixtures at substantially reduced dosage rates.
